Raspberry Pi 2: USB Flash Driver Error Mounting


Hello,

I would like to ask for the help with my problem. I am using SanDisk Ultra Fit 128GB USB 3.0 Flash Drive (SDCZ43-128G-G46) as my storage, and it's formatted as ext4. It works fine, but after an hour or so I get an error in GUI.
Code:
"Error mounting: mount exited with exit code 1:helper failed with mount: according to mtab, /dev/sda1 is already mounted on /home/pi/bitcoinData mount failed
I also tried to run dmesg. Here is the part of "abnormal" log:
Code:

I am not sure I understand what the problem is. If someone could helped me to resolve this issue I will really appreciate that.
As a side note, I do not recall this happening before rpi-update.

Edit: Another problem that I've faced after this error is that I can't turn off or reboot rpi 2.

I have had similar issues with ext4 in flash drives. Under heavy load they tend to fail.

Try running fsck.ext4 on the drive to repair any errors.
